Thread Subject: Skip a part of the signal

Dear Friends,

         I want extract the signal values only after 1sec of the simulation time or a part of the signal (Because in the beginning the signal starts at '0' which I don't need), as my signal repeats the same MINMAX values for long simulation times.

How can I get this part of the signal for further signal processing?

Thanking you in advance.

Prashant

Prashant:
"I want extract the signal values only after 1sec":
Figure out what index corresponds to 1 second (let's say it's 20) then
do this:
extractedSignal = originalSignal(20:end);

"or a part of the signal ":
Decide on a start index and a stop index and do this:
extractedSignal = originalSignal(startIndex : stopIndex);

Sorry, I have not mention that I am using simulink. I think this I have to do it for matlab code what you have suggested.How can I do it in simulink?

I don't have Simulink so I'm not sure. I thought Simulink code was
more or less compatible with MATLAB code bu I don't know. Maybe
there's some kind of "clipping" module??? I'm sure someone else will
supply you with an answer.

Thank you for the reply.
